Checking a VP44 on a Dodge Ram 2nd Gen Cummins

[@Tibidomj]

Ok..for any doubters out there! My truck has been down since december because i figured the vp44 was shot. I came accross this video and thought I would do all he said except the grounds. I just didn't think it could be that. Everything else checked out so all I could try was the grounds. And after cleaning all the grounds, the damn thing started right up and I saved a couple grand. Thanks for the great advice!

[@ChadMyers73]

Thank you and thanks for watching!

Our truck just stalled in the middle of the road and now we are at this step and your videos are wayyyyy helpful. Thank you!

I do a complete ground inspection/cleaning once a year. Just pick the nicest day in the spring or summer (no need to break a sweat), power wash your rig top, bottom & side and go over every ground you can find. Remove the ground if in doubt and clean/sand the connector and body to get down to bare metal. A little dielectric grease on the connection and you're good to go. Trying to locate an intermittent ground along the side of the road at night will drive you insane (been there).

[@ChadMyers73]

Great idea!

[@sherrytop2591]

Any normal test light will check grounds, just put the clamp for the light on the positive battery terminal. Then touching any good ground with the light probe will light the light.

[@ChadMyers73]

True but a test light does not show voltage.

[@willsull22]

⁠@@ChadMyers73correct, but the light puts a load on it. Light stays lit solid and consistent. A meter will show the voltage, but without any load. Pros & cons both really

[@beiza762]

Very helpful information. Will definitely look back to this once my VP44 acting up.

[@ChadMyers73]

Thank you for watching!

[@jamesdavis6275]

Harbor freight sells a probe that checks positive ( red light ) and negative/ground ( green light ) . It works decent for checking wires and doesn't cost much

[@ChadMyers73]

Yes I saw they have it For sale on their shelves now.

[@keltonbook3742]

Went through his whole check list. I finally pulled the return line above the fuel tank and it finally started to kick off.

[@keltonbook3742]

This was after I replaced the returns behind the head and from the injector. Making sure the copper washers were good and the T connection was sealed properly. Make sure that line isn’t air locked

[@nategreenfield1349]

Great video I'm trying to diagnose my vp44. Truck won't start after it's hot until it cools and going down the road it struggles to get up to speed and that symptom comes an goes. I'd hate to buy a new pump if that's not even my issue. Everyone that knows this motor is saying it's the pump.

[@theowner9715]

They sell the led test lights that show hot or ground at Walmart and lots of other places

[@ChadMyers73]

I have saw those thanks for sharing

Ever seen one that keeps getting the P0216 error code and the truck still runs great? My 02' has been getting the P0216 code for several years now.

[@ChadMyers73]

No I haven’t

[@rosshoffman7377]

Any solution to your p0216 code? You’ve had it for several years? Does it ever clear?

[@justinpenn3927]

Just bought a dually with this code, but truck runs fine, starts fine, previous owner thought it needed a vp because of the code

[@formetopoopon2057]

@@rosshoffman7377 No, mine has been getting the P0216 error code for about 5 years now. The truck still runs great. You can clear the code but it comes right back. I guess I'll just run it till the VP44 dies.

[@jamesdavis6275]

I've got a 01 3500 with 24v that keeps showing the p0216 code and mine runs great but I'm having issues with my throttle response. I've replaced the apps/tps 3 times and reset it a few times and now it keeps popping up with p0222 and a p0121 code . Both are tps sensor codes . Any advice would be great . Times like this makes me wish I could've found a 12v instead

sounds a lot like a grounding problem you found. Check out Military battery ends, You will love them!

[@russellminix6609]

My truck was throwing a crank shaft sensor code. I change the sensor now it would start. I checked all my grounds. It has fuel pressure I’m at a complete lose. Do you have any idea on what it could be? The check engine light went off after changing the sensor but now it won’t start

[@russellgatlinjr6477]

My truck runs and drives but it goes in limp Modelike if I press a gas pedal aint doing nothing and then I got a code for the injector/VP 44 and timing. Don't know where to start. Besides buying a new VP 44 and don't really want to do that.

hello, the vp 44 pump works directly connected to pin 6e 7 battery.thanks

[@freightshakernation9429]

This video is really going to help me out this weekend. When I was driving home today my truck completely died and cut off and now won't crank back up so I towed it back home. My lift pump is good so I'm guessing it's my vp44 because the truck cranks over fine just won't fire off.

[@ChadMyers73]

Hope you get it figured out. I have a couple of vp videos on my channel.

[@eddiebartlett5972]

My truck did the same. It was below 0 here in Colorado. Wont start. I replaced the Fass filters. Still won’t start. Hopefully it’s just air in the lines. Great video. 2001 2500 6speed 5.9L

[@freightshakernation9429]

@@eddiebartlett5972 I changed my filters and cracked my injector lines until fuel started coming out and then tighten them back up and the truck cranked back up and has been fine ever since!

I have a 2002 5.9l 24v and it has a p0216 code. Injector pump doesnt have 50 miles on it. It has stock lift pump in the tank that was replaced recently. Starts up with 15 psi of fuel pressure. Any ideas to fix it before the new vp44 goes bad again?

[@juliemiller9857]

I have put an air dog on my 99, it only comes on when I turn the key off, only for a ces. And thing you can think of that I can do for this??

[@ChadMyers73]

Sounds like it’s wired wrong

[@sharkyrich4844]

With a test light you check ground by connecting it to the positive terminal, lol. Holy shit.

[@alespretor27]

What if I have voltage on pin#5 all the time when key is on? What pin#8 does actually, what voltage should be present there?

[@coatneyadkins9005]

My brother my brother, i hope you see this and respond, I'm working on one of these in a forklift and it originally had a mechanical lift pump, i ran an aftermarket electric pump from the tank... Is there any trouble that could cause?

[@ChadMyers73]

I don’t think it should be a issue

[@spencerboisen3526]

Mine only starts with a wiff of either no matter how hot or cold

[@ChadMyers73]

I can see it in the cold

[@nicelemaggard1518]

my truck is acting like it ain’t getting full fuel. it starts, runs, and drives.. just doesn’t want to go when you start driving. i cracked the fuel pump and it squirts out fuel like it should. great pressure there. but i don’t wanna replace the injection pump without knowing thats it for sure. any ideas for me?

[@ChadMyers73]

Did you make sure all injectors are getting fuel

[@rezasap9471]

I’ve been having an issue with acceleration when my truck is cold. I hooked my scanner up and drove the truck and it says I’ve got about 11.4-11.8 volts at my vp44 depending on rpm. I’ve already replaced the pump but I guess I’ve got a wiring problem or ecm issue?

[@ChadMyers73]

Possibly the TPS also

Maybe off topic a bit..... But i just bought a 2002 24v , and I've replaced the oil and later on noticed that i was overfull, and smell diesel.... Thought i had Leakey injectors, so pulled them out, took them to get them test and turned out to be ok, replaced the copper washers on them and installed them back, replaced oil and sti have that same problem...... Any help would be appreciated on tips to where to go from here

[@ChadMyers73]

Could be a cracked head or crossover tubes.

[@raulortega9468]

@@ChadMyers73 thank you for taking the time to help.... I thought of a cracked head or piston, but i have no blow by at all, the engine does not misfire or nothing, once it starts it runs flawlessly, could the vp pump be a possible cause???

Check all of your grounds under the hood but other than that it could be the ecm or wiring harness

[@camojay79]

I am not getting 12 volts to relay pin 37 with key on. What might cause this?

Check fuses in the cab and all your grounds.

Checked all grounds, sent ECU off to get checked twice, gauge cluster tests good. Anything else you can think of before I replace engine harness and relay board under hood? Thank you for replying.

[@jimgreenly7941]

I have a 1998.5 RAM 2500 5.9 24 valve Turbo Diesel that is throwing a code P0216 "Injection Pump Timing Failure" I received a quote from the mechanic for $6,350 to replace the VP44 pump and all fuel injectors. He says the fuel pressure is 10 pounds and should be 8 pounds and the excess pressure is resulting in the diesel fuel foaming up and not staying in a liquid form. Does this sound right? Many thanks for the information!

[@ChadMyers73]

No my vp always has a Constant supply pressure of roughly 19 pounds from my AirDog

[@jamesdavis6275]

10 pounds sounds low to me . The 8 psi he mentioned is what the old ford 7.3 idi diesels require . I've got 14 psi on mine and I haven't done any upgrades to it however it does have a in tank lift pump but I'm not sure if it's a aftermarket brand like air dog or fass etc . I'm not too familiar with these cummins but based off my research you have to have atleast 5 psi at the very minimum or it'll damage the vp44 . I'm no expert so somebody correct me if I'm wrong always open to any help/advice knowledge I can get

[@ThrockRocket]

Buddy! I am having issues with my 2000 24v 5 speed. She starts every time and she idles great for the first 5 mins then she runs rough and rpms bounce between 800 to 1000. If i give a tad of throttle she jumps to 1050rpm and will not come down until i put it in gear. When driving it she seems ok until I start coming to a stop then she idles too high making it harder to slow down. Also when I rev it in idle to about 2k rpm it sounds like its hesitating/stumbling. Here is a video of that.. kzbin.info/www/bejne/lYSVhKCfht2aaa8 Sound like a fuel issue to you? Any help is appreciated! Thanks so much! i wanted to check the fuel pressure but not sure how since my filter canister has been removed.

[@ChadMyers73]

I do think it’s a fuel issue but it could be a multitude of things I would check for air leaks in your fuel system could be a bad injector could be a PCM issue with the VP 44. Check and see if there’s any codes stored and start checking for air leaks in your fuel system.

[@ThrockRocket]

@@ChadMyers73 come to find out the new "Bosch" injectors I installed about a month ago are not real bosch lol. Had them pop tested and shop said they were between 220 and 250. So he said they were junk lol. Lesson learned not to buy injectors on Ebay haha.

You should only have power to pin 5 for about 3 or seconds after you turn the truck off.

Hot wire vp???

[@ChadMyers73]

Yes the safest way to do it would be with a breakout box. Otherwise you just take a ground and a power wire and hook it to the corresponding leads on the plug.
